This article develops a framework to analyze how political actors adopt social media in systems characterized by clientelism and populism, tracing the consequences and disruptive capabilities of the forms of social media adoption. The framework proceeds in two analytical stages. The first locates actors’ structural positions in the political system (internal/external) and their relationship with the mainstream media (allied/antagonistic). The second builds on pragmatism focusing on iterative problem situations actors face that explain forms of social media adoption. In examining the (...) structural positions and problem-solving stages of Colombian political actors, this article articulates three paths of adoption: habit preservation, internal innovation, and external innovation. Preservationists understand the new technology in old terms, projecting their understandings of old media onto the new one. Internal innovators combine clientelist practices and communication ones, upholding core routines while integrating new ones; they show a potential to reshape the system internally, making viable part of it, but changing the balance of power between existing elites. External innovators develop practices that integrate physical spaces and online communication, displaying a disruptive potential for existing core practices and the political system. In this way, the framework and empirical case link and develop the literatures on clientelism and political communication. (shrink)
